CEMENT-APPLIER.

Specification of Letters Patent.

Application filed December 11, 1907.

Serial No. 406,057.

is provided with a strip of cement in locations where it is desired to form a turnedover edge or bead by bending the edge of the stock back upon itself, the cement maintaining the edge in beaded form, or for holding the stock in bent position until the same-may be permanently sewed in subsequent operations. In practice cement is also employed for temporarily securing together the parts of a given article, such as a shoe, boot or slipper, as for instance, fortemporarily securing the linin to the upper, so that the parts may not be misplaced during oper-' ation. One of the methods, heretofore in quite general use has been to apply this'cement by hand with a brush, but I find this method objectionable because of the Waste of cement occasioned thereby and because it is impossible to apply the proper width of cement with speed to the parts. This method is also dangerous. The cement is viscous and is also highly inflammable. The cement being viscous or stringy, a large amount of cement is wasted between the cement-pot and the pointwhere the cement is applied onaccount' of the cement stringing between the brush and pot when the brush is removed from the body of cement in the pot after dipping the same therein.

The cement usually employed in work of this character is a-composition containing rubber and benzin. It is of course obvious goods back into the cement-feeding. channels and thereby clogs the feed of cement to the roller.

It is the object of my invention to avoid these objections and to provide a cement-applier capable of applying a strip of cement of proper width and to utilize the viscous.

or stringy'properties of the cement in the application ofthe same to the goods, and further to provide a container for the cement from which it may be fed without exposure of the same. v a I The invention will be readily understood from the followin description and claims, and from the drawings, in which latter:

Patentedsept. e, 1910.

Figure 1 is a front elevation of my improved device. Fig. 2 is a side elevation of the same. Fig. 3 is an enlarged front view of the applying head in connection with the stock-support. Fig. 4 is a side elevation of the same. Fig. 5 is a horizontal section taken -on the line 22 of Fig. 4, showing a top View of the stock-support and the connection with the column. Fig. 6 is a vertical section taken on the liney-y of Fig. 1, partly broken away. Fig. 7 is a front elevation of the head with the feeding-foot removed for showing the feeding opening in the head. Fig. 8 is a bottom perspective view of the feedin -foot.' Fig. 9 is a crosssection of the feeding-head on the line a2-m of Fig. 4. Fig. 10 is a cross-section on the 'line 'w of Fig. 4, showing the connection between the stock-gage and the stock-support. Fig. 11 is a vertical section on the line yy of Fig. 1 showing the supply-valve closed ready for the insertion of a piece of stock between the feeding-foot and stock-support; and, Fig. 12 is a slmilar view with a piece of stock introduced between the feeding. foot and stock-support.

1 represents a columnon'which there is a container 2.

3 is the applying-head which is connected with the container by a feeding-pipe 4 in which I prefer to provide a. stop-cock 5. The head communicates with the container so-that the cement in the latter may have for furnishing the supply of cement when the applier is being used. Y

7 is a stock-support shown as a table composed of a bracket 8 secured to the column. This table is preferably adjustable vertlcally on the column as by means of a slideway 9 between the table and column and a bolt 10 passing through a slot 11 in the table and into the column.

The head is provided with an opening 15 communicating with the passage from the container, and the foot is provided with a transverse passage 16 from which a longitudinal aperture or apertures 17 extend to the bottom of the foot. I prefer to provide a plurality of these longitudinal apertures and to connect the same at the bottom of the foot by a transverse groove 18 in which the cement is adapted to spread so that the cement may be applied in unbroken width.

I prefer to provide the bottom of the pressure-foot with projections 19 extending longitudinally of the passage of the stock, as indicated by the arrow (1, depressions 20 being located between the. projections. I further prefer to provide the stock-support with longitudinal projections 21 between which depressions 22 are located, and to cause the projections 19 to register with the depressions 22, the roject-ions 21 registering with the depressions 20 so that when the feeding-foot is depressed the respective pro jections may lie in the opposite depressions. The head is preferably attached to the pipe 4 by means of a threaded connection 23 and locked in place by a jam nut 24 for roviding adjustment whereby the projections of the foot may register with the depressions on the stock-support, andvice versa. If now a piece of stock shown at 25 is inserted between the feeding-foot and stock-support, the feeding-foot will be raised not only to the extent of the thickness of the stock, but .will be further raised to the extent to which the projections respectively extend into the depressions for providing a substantial opening at the valve 26 for the passage of cement therethrough. It will be noted from Fig. 11 that when the feedingfoot is depressed to fullest extent that the valve 26 is just closed and that any. upward movement of the feeding-foot will open the valve, the extent of movement being indicated by a comparison of Figs. 11 and 12.

To provide wide opening at this valve I form the mating edges of this valve with straight faces as shown respectively at 27 and 28 respectively at the opening 15 and transverse passage 16.

In order to cause depression of the feeding-foot, I provide a spring 29 secured to a screw 30 on the feeding-foot and a screw-31 on the retaining-plate 32. The feeding-foot, which in the form shown also constitutes a pressure-foot, is preferably provided with upright grooves 33 for reducing the friction between it and the channel 34: in the head in which the feeding foot moves. These grooves also act as oil-passages to loosen the cement if any should work in between the foot and its bearing.

For adjusting the limit of descent of the feeding-foot I provide a set-screw 35 in :1 lug 36 on the feeding-foot, the set-screw striking the head and being held in place by a jam-nut 37.

38 is a. stock-gage adapted to be secured at suitable points on the stock-support so that the cement may be applied either at the edgeor away from the edge of the stock. I accomplish this adjustment by providing the stock-support with a slot 39, a headed bolt 40- passing through said slot and the gage, a nut 41 clamping the parts in adjusted position.

The projections and depressions on the feeding-foot help to spread the cement. The cement deposited in the transverse groove 18 contacts the surface of the stock being cemented while the same is passed under the feeding-foot. This deposit is then acted on by those parts of the projections in rear 01' at the feeding-out side of said groove, which permits the cement to pass through the depressions at the feeding-out side of said foot in sufiicient body to fill the interstices of the surface of the stock and to press the cement into the same, the stringy properties of the cement tending to aid the feed of the cement by drawing the same away from the groove and feeding apertures, the cement thus with drawn being instantly replenished from the supply above. The cement is compacted into the stock and spread throughout the width of intended application and prevented from spreading beyond such intended width. The

projections also reduce friction between the stock and the feeding-foot and support.

In order to-aid the ready insertion of stock between the feeding-foot and stocksupport I preferto provide the under surface of the foot with a forward upward curve as shown at 42, which is preferably located at the under face of the toe 43 of said foot, and to provide the edges of the foot and table respectively with slopes 44 and 45.
